What is the true purpose of human life, according to the philosophy presented in Chapter 8 of the Sai Satcharitra?

According to the philosophical discussion in Chapter 8, the true purpose and duty of human birth is the attainment of the Supreme Self, or Paramatman. The text argues that a life spent merely on survival is wasted. It questions if the purpose of life is simply to be born, grow strong, and live a long time, suggesting this is insufficient. The chapter contrasts this higher purpose with a life focused only on the four activities of eating, sleeping, fear, and mating, which it states would make a human birth useless and no different from the existence of a dog or a pig. True success, as described in Chapter 8, is the realization of the Eternal, which makes a human being truly free, fearless, and independent.
